Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?

It is possible to use the increment operator ``{plus}{plus}``, to set the value of a ``++bool++``({cpp}) or ``++_Bool++``+(C)+ variable to ``++true++``. But this feature has been deprecated in {cpp} since the 1998 version of the standard, removed in {cpp}17, and even where allowed, is simply confusing.

Same is allowed in C, but seems that was not deprecated:
|
|
|
|
{noformat}
|
|
|
|
void fun() {
|
|
|
|
_Bool b = 0;
|
|
|
|
b{plus}{plus};
|
|
|
|
}
|
|
|
|
{noformat}
|
|
|
|
So [~freddy.mallet] could you please update spec? Also could you please add reference to exact version of standard about deprecation in order to not be unfounded?

\[~ann.campbell.2] description is about "{cpp}", whereas increment of boolean is allowed in C also.
